Force feedback mouse wheel

Abstract

A force feedback wheel is provided on a mouse or other interface device manipulated by a user. A sensor detects a position of the mouse in a workspace and sends a position signal to a connected host computer indicating that position. A rotatable wheel is mounted upon the manipulandum and rotates about a wheel axis, where a wheel sensor provides a wheel signal to the host computer indicating a rotary position of the wheel. A wheel actuator coupled to the rotatable wheel applies a computer-modulated force to the wheel about the wheel axis. The mouse can be a standard mouse or a force-feedback mouse, where forces are applied in the mouse workspace. The host computer is preferably running a graphical environment, where the force applied to the wheel can correspond with an event or interaction displayed in the graphical environment. The wheel can also be included on other devices such as remote controls and radios.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates generally to interface devices for allowing humans to interface with computer systems, and more particularly to mechanical computer interface devices that allow the user to provide input to computer systems and provide force feedback to the user. [0002] Computer systems are used extensively in many different industries to implement many applications. Users can interact with a visual environment displayed by a computer on a display device to perform functions on the computer, play a game, experience a simulation or “virtual reality” environment, use a computer aided design (CAD) system, browse the World Wide Web, or otherwise influence events or images depicted on the screen. One visual environment that is particularly common is a graphical user interface (GUI). GUI's present visual images which describe various graphical metaphors of a program or operating system implemented on the computer. Common GUI's include the Wi...

Benefits of technology

[0006] The present invention is directed to an interface device which is connected to a host computer and provides a rotatable wheel having force feedback. The force feedback wheel provides greater functionality and relays greater tactile information to the user concerning the control task being performed with the wheel than a standard non-force-feedback wheel.

[0011] The apparatus and method of the present invention provides an interface device including a force feedback wheel that allows a user to conveniently provide input to manipulate functions or events in a host computer application program or electronic device. The force feedback wheel allows substantially greater control and flexibility than previous mouse wheels or other knobs, and the force feedback allows the wheel to control a variety of useful functions in a graphical environment which prior wheels are not able to control.

Problems solved by technology

One drawback to traditional mice is that functions such as scrolling a document in a window and zooming a view displayed on the screen in or out are typically awkward to perform, since the user must use the cursor to drag a displayed scroll bar or click on displayed zoom controls.

One problem with existing mouse wheels is that they are quite limited in functionality.

Even the mouse wheels having physical detents are limited in that the detents are spaced a constant distance apart and have a fixed tactile response, regardless of the scrolling or zooming task being performed or the characteristics of the doucment or view being manipulated.
